Natural gas fueling stations are currently scarce.
1. Who's going to retrofit 100,000 or more service stations for natural gas. Is Swiftoboat Pickens going to pay for that?
2. The tanks and valves for CNG are supposedly crash-proof. I still wouldn't want to be within a quarter of a mile when some sociopath t-bones another driver.
3. How will this NG get distributed to filling stations? Will there be thousands of CNG or LNG trucks making daily deliveries? When some of them crash, it ought to make for interesting news stories.
